Could be a safety , like evaporator probe holding compressor out.

Some manufactures use this as a freeze up safety if the evap coil temp gets below say -11deg C

More info may be of some help.

Covers OH&S also.

But unless there is no stock , I think there will always be window shoppers , or people that just like to inconvenience us as much as possible.

Some useful info for another time , after being in design of cabinets & cases of the cap tube variety , most only run at 1K subcooling.

Have seen this on small cabinet freezers , from manufacture new solenoid hammering hot gas to coil , spring tension on danfoss valve incorrect , hence not seating correct.

Ahhh , that is going straight to the library :spitball:

Totally agree , a compressor efficiency test will tell you with 100% accuracy if it is doing the job it has been designed to do.

The manufacturer will tell you that a cap tube system is critically charged , they are to some extent but you can cut off up to 200mm on some and be confident that it will still run to design...

Why not have it on auto mode with a timer in the outdoor unit to start + stop ?

Manitowoc requires you to use one of these so as to not interfere with the charge , they do work.

Is it mandatory to lock-out & isolate the supply like it is here in OZ. :.02:

I beg to differ with the price shown in Australia $3.84 Gallon

There is no condensing of refrigerant so it is called a gas cooler , it boils off at around 32 Degrees c
